Dianthus plant named &#39;wp08 ver03&#39;

ABSTRACT

A new cultivar of  Dianthus  plant named ‘WP08 VER03’ whose flowers are pleasantly perfumed, double and bi-colored lavender-pink with a maroon “eye” and comprised of deeply fimbriated petals. In combination these traits set ‘WP08 VER03’ apart from all other existing varieties of  Dianthus  known to the inventor.

GENUS

DIANTHUS

SPECIES

×hybrida

DENOMINATION

‘WP08 VER03’

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(f) of the application for a grant of European Community Plant Breeders Rights which was filed for the instant plant variety on Jun. 30, 2008, Application Number 2008/1507.

The present invention relates to a new and distinct cultivar of hardy garden pink or carnation which is grown for use as a flowering plant for pots and containers and for planting in the garden or landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘WP08 VER03’.

‘WP08 VER03’ is a complex hybrid plant that is the product of a breeding program started by the inventor in 1985. The breeding program is conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The inventor selected ‘WP08 VER03’ in 2003 for its flowers which are double and bi-colored lavender-pink with a maroon “eye”. The petals of ‘WP08 VER03’ are deeply fimbriated and flowers are pleasantly perfumed.

‘WP08 VER03’ resulted from the open pollination between the inventor's unreleased and unpatented seedling selection Dianthus code number WE03 as female parent plant and an unknown seedling as male parent plant.

‘WP08 VER03’ is distinguishable from the female parent as follows: Whereas ‘WP08 VER03’ bears double flowers which are colored lavender pink with a maroon eye, the flowers of the female parent are semi-double and are colored white with a dark magenta eye.

The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP08 VER03’ is the inventor's variety, Dianthus ‘Devon Esther’ (U.S. Plant Pat. No. 18,222). ‘WP08 VER03’ is distinguishable from ‘Devon Esther’ as follows: The flowers of ‘WP08 VER03’ are more fully double with greater fimbriation of the petals than the flowers of ‘Devon Esther’. The flowers of ‘Devon Esther’ are darker purple-pink in color than the lavender-pink color of the flowers of ‘WP08 VER03’.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 2003 in a cultivated area of Houndspool, United Kingdom. The method of asexual propagation used was vegetative cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP08 VER03’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP08 VER03’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.

1. Dianthus ‘WP08 VER03’ exhibits a compact habit.

2. Dianthus ‘WP08 VER03’ blooms profusely from April until October.

3. The flowers of Dianthus ‘WP08 VER03’ are double and bi-colored lavender-pink with a maroon “eye”.

4. The flowers of ‘WP08 VER03’ are pleasantly fragrant.

5. The petals of the flowers of ‘WP08 VER03’ are deeply fimbriated.

6. Dianthus ‘WP08 VER03’ exhibits grey-green foliage.

7. At maturity, the height of the foliage mound of Dianthus ‘WP08 VER03’ is 20 cm to 25 cm; the width is 10 cm to 12 cm.

8. Dianthus ‘WP08 VER03’ is perennial and is hardy to −15° C.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Dianthus variety ‘WP08 VER03’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘WP08 VER03’.

The drawing labeled as FIG. 1 depicts an entire flowering plant.

The drawing labeled as FIG. 2 depicts a close-up view of the flower.

All drawings were made of 9 months old plants which have been grown in 1.5-litre containers in a cold glasshouse in Devon, United Kingdom. No chemicals were used to treat the plants. All drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘WP08 VER03’. Data was collected in spring from 1.5-litre container plants in spring, and grown indoors in Devon, United Kingdom. The color determinations are in accordance with the 2002 edition of The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The colors of stems, leaves, calyx, and epicalyx have been noted on plants which retain the characteristic waxy bloom of Dianthus. No chemicals were used to treat the plants. Growing conditions are typical to other Dianthus.
